Spreadsheets are among the most commonly used applications
for data management and analysis, Since they are easy used and mostly can be found in the free market.
However, the spreadsheet paradigm of computation
still lacks sufficient analysis and concrete semantics that we can depend on.
In this chapter, we will try to set semantics and demonstrate how we can represent a relational
schema (database) into a spreadsheet. We will only use the spreadsheet functions and operations that can be 
done on the cells. Most of the concept of the conversion from relational models to spreadsheets and the given examples 
were introduced in 
\cite{tyszkiewicz2010spreadsheet}.
